Can't see COVID-19 Exposure Notifications send with Android.

I use the beacontools for my project, "CoronaTeller" (dutch for Corona counter)

Testing :

  $ bluetoothctl
  [bluetoothctl]scan.transport le
  [bluetoothctl]scan.uuids 0xfd6f
  [bluetoothctl]scan on

Gives all beacons including the Android phones. Running the beacontoools scan tool (without any packet filtering) gives only my iPhone, not an Android phone.

Unfortunately I don't have an Android phone to test that. Can you provide me with a raw dump of the ble packet?
You should be able do get it using:

sudo hcitool lescan --duplicates
# (in another terminal)
sudo hcidump --raw | grep --line-buffered  "6F FD" -A 1 -B 1

I just published 2.0.2 in which I made packet pre-filtering more resilient against slightly different packet layouts. This should the issue.

Tested, seems to work. Great work, thanks @citruz
